'With' reference to'the' drawing, I have illustrated a carton shellgenerally indicated by the numeral 10 and a carton co'ver or lidgenerally indicated by the numeral 12 hingedly connected to a' rear wall'14 of the carton shell 10. v

The carton shell also includes a front wall 16 and end Walls 18 and 20.The rear and front walls 14 and 16 are formed from continuations" of andperpendicular to a bottom wall 22. n z End walls 18 and 20 are securedin the vertical positionby any selected suitable means, as for exampleas illustrated, there are end extensions 24 formed as ,continuations ofthe rear-"and front walls 14 and 16 and adhesively attachedtothe-internal surfaces of the end walls 18and 20.

This invention is a self-supporting flap of a carton cover with lockingmeans between the carton shell and cover.

This invention has a great number of uses as for example in packaging ofjewelry or food or any other suit-- In the first embodiment of myinvention shown in solid line in FIG. 3, I provide a pair of lockingflaps 26 and 28 hingedly connected to and forming upper extensions ofthe "end walls 18'and 20 respectively. Locking flaps 26 and-'28are'folded over in a horizontal plane to provide detail.

able product. By providing a releasable locking cover, the

contents are secured against any inadvertent opening of the cover, andare particularly suitable for reclosure;

There are anumber of cartons having locking tabs .be-, tween the cartonshell and the carton lid for this purpose. As for example, Phillips2,544,565, Dunning 2,839,236; Van Rosen 2,741,418, Barrington et 211.,2,768,777, Osteen 2,777,629. However, it will be noted that with eachrofthese cartons of the above-mentioned prior art, it is neces: sary in thecover construction toy provide not only the; cover and depending frontwall of the cover, butalsoa pair of end side Walls hinged to the coverand adhesivelyi attached to the front cover wall in order -,to maintainthe front and top cover walls in closed and in locked rela-, tionshipwith the carton shell.

It is Significant object this mventwn Provlde Spaced'frorneac'hothe'rfthereby Providing a differential an improved carton constructionwhereby the front wall of the coveror lid is self-supporting thereby toeliminate the need for cover end sidewalls. This substantially reT ducesthe problems of forming andgluing the carton.

The'cove'r 12 comprises an external or first top cover cover"- 12, Iprovide an external locking flap panel '32' and an internal locking flappanel 34hinged (along what is referred to in the claims as both afsecondinterconnecting means and a third hinge line) to and folded under theexternal locking flap panel 32. The internal locking flap panel 34 ishinged at its upper edge, when elosed-,"along'a second scored hinge:connection 36 to an internal or second top cover 'wall 38; it will beunderstood that this secondtop cover wall 38 need notbe substantially'c'oexte'nsive with the cover 30, "but need only have sufficientsurface' area to secure the panel 34 in fixed spaced relationship withthe panel 32."'The external and With the invention herein described,itis possible for the carton manufacturer to preglue the lid in a mannerso that the carton can be shipped flat, and assembled at the point ofpackaging.

It is an important object of this invention to provide a cartoncomprising a base having walls forming a carton shell open on onesurface with a cover hingedly connected to one wall 'of the carton shelland the cover having a pair of cover flap panels facing each other andhinged to each other and to the cover, and the hinge lines of the coverflap panels being so arranged so as to provide a self-supporting forwardcover flap adapted for closure with the carton shell.

Other objects and advantages of this invention will be particularly setforth in the claims and will be apparent from the following description.

FIGS. 1 and 2 are left end elevational views as viewed in FIG. 3 of oneembodiment of my invention with the cover shown in an open and closedposition respectively.

FIG. 3 is a perspective view of the FIGS. 1 and 2 embodiment, and

internal top cover walls 30 and 38 are adhesively attached together inamanner whereby the two hinge connections 31 and '36 (hereinafterin theclaims referred to" as a first interconnection means) extend paralleland are hinge construction between the external'paneli32 and theinternal panel 34an'd connected tothe external top coverwall 30 therebyto maintain the combined cover or locking fiap 32-34, generallyindicated by the numer'al 33," in'a self-supporting substantiallyperpendicular from thehinge connection '31, also p'ermits folding underof'the' locking flap' 34 so that it may be preglued by the cartonmanufacturer, tuck'edunder and shipped flat with the flat carton shellto the packager. It will be understood that the carton shell 10 iserected by the packager and at that time the locking flap 33 assumes thebroken line position shown in FIG. 1 and solid line position shown inthe other figures.

When the carton shell 10 is erected and the cover 12 is moved from theopen positions illustrated in FIGS. 1 and 3 to the closed position FIG.2, the locking tabs 29 and 30 are received in locking relationship withside slots 40 and 42 provided along the hinge line 36, into the spacebetween the parallel spaced hinge connections 31 and 36.

In the second embodiment of my invention illustrated in FIG. 4, allnumerals of identically the same elements as the FIGS. 1-3 embodimenthave the same numerals followed by the suffix B. I provide an insertportion 43 for the carton shell formed from a continuation of the frontwall 16 and out along the lines 45 and 46 part way into the front wall16 and folded down to a score line 48. The insert 43 extends across thecarton shell parallel to the bottom wall 22 and terminates in a glueflap 50 adhesively connected to rear wall 14. I provide only a singlelocking tab 44 projecting forwardly of front wall 16 by cutting aU-shaped out line below and terminating at the scored fold line 48.Thus, when the insert 43 is folded to the illustrated position, thesingle locking tab 44 projects forwardly of wall 16 and is received inlocking relationship with a U-shaped out line 52 in internal lockingflap panel 34 when the cover 12 is closed to the FIG. 2 position.

While there is hereinabove described the preferred forms of thisinvention it will be apparent that various modifications and changes maybe made therein, without departing from the spirit of this invention asset forth in the appended claims.
